Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory

See original GitHub issue

Investigative information

Please provide the following:

Timestamp: 2018-02-01T16:15:00.0130000Z
Function App version 2.0-beta
Function App name:
Function name(s) (as appropriate):
Invocation ID: f17310a1-65a3-4468-a706-acc511fb9449
Region: North Europe

Repro steps

Provide the steps required to reproduce the problem: I’m using Microsoft.IdentityModel.Clients.ActiveDirectory nuget package version 3.19.1 to connect authenticate to Azure Batch

The auth code is :

    public static async Task<string> GetAuthenticationTokenAsync(string tenantId, string clientId, string clientKey)
    {
        AuthenticationContext authContext = new AuthenticationContext(_AuthorityUri + tenantId);
        AuthenticationResult authResult = await authContext.AcquireTokenAsync(_BatchResourceUri, new ClientCredential(clientId, clientKey));

        return authResult.AccessToken;
    }

Exception message is :

Exception while executing function: GetTaskCounts Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=3.19.1.3001, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621) Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=3.19.1.3001, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Whenever this code is called there is an exception being raised with the below stack

We are experiencing this exact same issue, for a C# compiled function targeting .NET Core (Azure Functions v2), running the function locally, with Microsoft.IdentityModel.Clients.ActiveDirectory v3.19.4

We had to downgrade to 3.14.0, as recommended by @phinguyenit

dotnet remove TokenExpiration package Microsoft.IdentityModel.Clients.ActiveDirectory
dotnet add TokenExpiration package Microsoft.IdentityModel.Clients.ActiveDirectory --version 3.14.0

Update: It seems that 3.16.0 is the most recent version that does not cause an issue.

dotnet add TokenExpiration package Microsoft.IdentityModel.Clients.ActiveDirectory --version 3.16.0

Starting with 3.16.1 and on, we experience this issue.

After running into this problem in one project but it working in another, there is something else you can try, which is “downgrading” to the full framework and the previous version of Azure Functions. To do this, change the TargetFramework in .csproj to net461 and remove the line <AzureFunctionsVersion>v2</AzureFunctionsVersion>. If you do not remove the v2 line, you will get a blunt Fatal Error when you try to run the function.
